is covered with long erect white pubescence ; second joint very small, 

 about one- thirds as long as the basal joint, in colouring" similar to the 

 latter, on the apical margin there is a distinct (though small and nar- 

 row) dorsal process and a circlet of tiny black bristles which become 

 longer and conspicuous beneath at where there is some long white 

 pubescence intermixed ; third joint usually, darker dorsally, rather nar- 

 row, the first annulation about twice as long as its broadest part and 

 with the roundish dorsal hump near the base, on this hump there are 

 very few tiny black bristles ; the style-like portion of the third joint 

 narrow and conspicuously pointed at the apex, with very faint annula- 

 tion, more than two-thirds the length of the basal annulation of the 

 segment, with very few tiny hairs especially on the top. Eyes large 

 out rather fiat, with inconspicuous fine pubescence, in death deep black 

 with some metallic ruster ; in profile about one and a half times as 

 deep as the length, the frontal margin sloping in about 30% and the 

 lower angle being blunt and rounded but moderately produced below ; 

 when seen in front much more wider than the depth, the frontal angle 

 being about 125°, and the upper angle about 8o°, and the rounded 

 lower angle about 125 ; the facets all about equal in size. 



Thorax short, quadrate with rounded angles, blackish with ashy 

 grey tomentum, but the hind border still blackish, pubescence on the 

 disc mainly erect long black, but with some recurrent short white and 

 blackish hairs intermixed, the white one being only distinct about and

 the disc, on the front part there are almost only the fine long whitish 

 hairs similar to the erect black pubescence on the disc ; humeri mode-

 praealar calli triangular not very prominent, ashy grey with numerous 

 long shaggy blackish and yellowish hairs intermixed, and on the postero-
